ADTRAN's SmartOS gateways leverage Super-Vectoring

ADTRAN introduced its new SmartRG 652ac (SR652ac) residential and small business gateway with the ability to deliver highly competitive broadband—up to 700 Mbps — without service or customer disruptions via bonded super-vectoring (VDSL2 profile 35b) technology.

ADTRAN said this highly scalable fiber broadband extension technology is ideal for the rapidly growing MDU/MTU markets because it uses the existing in-building wiring to each unit. Further, service providers can run super-vectoring in parallel to other xDSL technologies in their access network, adding additional operational savings.

The SR652ac also provides advanced capabilities via its open software platform (based on OpenWrt), including self-service portals, self-healing Wi-Fi and subscriber analytics. When paired with the ADTRAN 1148SVX 48-port sealed broadband micronode, operators now have a highly scalable solution to create efficient and cost-effective whole-home and whole-business Wi-Fi environments without the time and expense of pulling new facilities to each unit.

“The design philosophy with SmartOS is to give service providers a single, open source-based, secure software framework so that providers gain consistency and commonality to reduce testing or qualification cycles and increase speed to market for new and innovative services,” ADTRAN’s Senior Vice President of Subscriber Solutions & Experience, Jeff McInnis, said. “We can significantly reduce the cost and resources required to introduce new solutions into a network and help our customers bring better services to their subscribers through our feature-rich, SmartOS platform—enhancing the experience for everyone.”

ADTRAN acquires SmartRG for Connected Home software platforms

ADTRAN has acquired SmartRG Inc, a supplier of open-source connected home platforms and cloud services for broadband service providers. Financial terms were not disclosed.

SmartRG, which is based in Vancouver, Washington, offers a portfolio of cloud-management, analytics, Wi-Fi-enabled residential gateways along with a SmartOS software platform.

SmartRG counts more than 3 million devices in service and over 1.3 million devices under management in North America, the Caribbean and South America. The company expects to scale and drive growth through its differentiated software solutions as more customers shift from closed, proprietary options to SmartOS—its open-source-based, cloud-enabled solution suite.

ADTRAN said SmartRG's Smart OS, together with its own ADTRAN Mosaic platform, provides full end-to-end management and orchestration solutions from cloud edge to subscriber edge. Service providers understand that bandwidth must now be delivered not only to the doorstep but down to every device within a home to meet consumer expectations.

ZTE boosts VDSL2 with 35b bonding

ZTE has added 35b bonding profile support to its VDSL2 CPE device. Profile 35b technology can provide downstream rates three times those of profile 17a by expanding the spectrum to 35 MHz.

ZTE said the 35b bonding profile enables the CPE to deliver 500 Mbps downstream and 100 Mbps upstream rates over a 200-meter telephone line.

The company noted that profile 35b and other profiles, such as 17a, can use vectoring technology in the same bundle of telephone line pairs, thereby bringing the speed of multiple line pairs in actual deployments close to the speed achievable in ideal noiseless conditions.

ZTE ZXHN H186 is designed as a bridge modem with two GE ports at the LAN side. If an existing home gateway is linked to a GE port of the ZXHN H186, its rates can be upgraded to up to 500 Mbps downstream.

ZTE has shipped over 280 million CPE devices to date.

ALU Achieves 10G over Copper Phone Lines at 30m

Bell Labs, the research arm of Alcatel-Lucent, demonstrated the ability to carry 10Gbps over traditional copper telephone lines over a distance of 30 meters.  Bell Labs also announced a prototype technology that can achieve 1Gbps symmetrical over existing copper access networks.

The Bell Labs tests used a prototype technology called XG-FAST, which is an extension of the G.fast standard being finalized by the ITU. When it becomes commercially available in 2015, G.fast will use a frequency range for data transmission of 106 MHz, giving broadband speeds up to 500 Mbps over a distance of 100 meters.

Bell Labs said XG-FAST uses an increased frequency range up to 500 MHz to achieve higher speeds but over shorter distances. Bell Labs achieved 1 Gbps symmetrical over 70 meters on a single copper pair. 10 Gbps was achieved over a distance of 30 meters by using two pairs of lines (bonding). Both tests used standard copper cable provided by a European operator.

Marcus Weldon, President of Bell Labs: “Our constant aim is to push the limits of what is possible to ‘invent the future’, with breakthroughs that are 10 times better than are possible today. Our demonstration of 10 Gbps over copper is a prime example: by pushing broadband technology to its limits, operators can determine how they could deliver gigabit services over their existing networks, ensuring the availability of ultra-broadband access as widely and as economically as possible.”

Ikanos Demos VDSL at 300 Mbps over 200m

Ikanos Communications has achieved an aggregate throughput of 300Mbps over a standard single-pair copper cable up to a distance of 200 meters (short-loop) using its existing VDSL chipsets.

Ikanos described the short-loop demonstration as a significant step towards G.Fast.

The demonstration follows recent, multiple top-tier OEM and carrier lab trials in which the company’s Velocity-3 central-office (CO) chipset was been given high marks for achieving 150Mbps aggregate throughput (110Mbps downstream and 40Mbps upstream) at a distance of 500 meters in a 192-port reference DSLAM system.

“Ikanos has a history of challenging the industry by pushing the performance envelope and continuing to raise the bar on our competition,” said Kourosh Amiri, vice president of marketing at Ikanos. “With Velocity-3, in a matter of a few months, we have received widespread recognition of our industry leadership in performance and scalability for high-port-count deployments of 192 lines (scalable up to 384), at distances reaching 500 meters and beyond.  While the G.Fast promise of gigabit performance is still on the horizon, our ability to demonstrate hundreds of megabits for lower-port-count short-loop configurations using our currently shipping CPE and CO silicon establishes Ikanos as the leader in the ‘pre-G.Fast’ era, as we enable telcos to remain competitive against mounting pressure from MSOs and continue to enhance the consumer DSL broadband experience.”

Alcatel-Lucent's G.fast Achieves 1.3 Gbps over 70m of Copper

Alcatel-Lucent announced G.fast access technology, which uses Bell Labs vectoring techniques and a wide frequency band to achieve very high speeds on copper lines over very short distances.  The company said G.fast is intended for typical applications of 500 Mbps at 100 meters or less. In recent demonstrations and under laboratory conditions, Alcatel-Lucent achieved 1.3 Gbps over 70 meters.  The technology is being positioned as an evolutionary step for VDLS2.

A trial conducted with A1, the Austrian subsidiary of Telekom Austria Group, first tested G.fast over a single, good quality cable, achieving a maximum speed of 1.1 Gbps over 70 meters and 800 Mbps over 100 meters. On older unshielded cables, typical of most in-building cabling in Austria, the trial achieved speeds of 500 Mbps over 100 meters on a single line. Although adding a second line introduces crosstalk, the use of vectoring can be used to maintain 500 Mbps over 100m. In comparison, DSL networks typically deliver speeds of 5-30 Mbps and VDSL2 vectoring networks typically supporting up to 100 Mbps.

Alcatel-Lucent said G.fast, which is not yet standardized, won’t be commercially available for several years.
